The last inert guards in `scheduler.ts`. Independent of my other branches. ## Inert-guard ratchet | Scope | Before | After | |---|---:|---:| | `scheduler.ts` | 5 | **0** | | total | 12 | **7** (triage.ts 8 → other worker; executor.ts 4 → #3112) | ## The live bug These read `resolveTaskParkedColumnsSync`, which answers with the **default** workflow in production. On a renamed board the scheduler **never woke** on unpause or planning-finish, and a **deleted blocker never unblocked its dependents** — the card sat behind a task that no longer existed. ## The criterion, restated because I got it wrong before **What blocks a guard is whether its answer is consumed synchronously — not whether the enclosing listener is declared sync.** I assumed the latter earlier in this program and reverted for it. All three fail that test: two only gate `schedule()`, which is itself `async`, fire-and-forget and re-entrance-guarded; the third already sits below an `await getSettings()`. The edge-trigger bookkeeping (`planningTaskIds.delete`) **stays synchronous** on purpose — deferring *that* would let a second update re-enter the branch. ## The union is load-bearing, not defensive Post-U11 the default lineage has no `triage` column, so a **resolved** answer returns `intake: "todo"` where the inert path fell back to `"triage"`. Converting without unioning the legacy ids silently **narrowed** the wake set and stopped waking cards in a legacy-named lane — caught by *"schedules when planning clears in triage"*. **A resolved conversion must be a superset of what it replaces, or it is a behaviour change wearing a vocabulary change's clothes.** That's the reusable lesson here. ## Tests - Drained with the repo's existing **`flushAsyncHandlers`** helper — written for exactly this fire-and-forget shape — rather than loosening any assertion. - **The characterization test flipped, as designed.** `workflow-scheduler-parked-columns-live-e2e.pg.test.ts` asserted *"a dependent in a RENAMED hold column is NEVER unblocked"*, with its author noting: *"expected to flip to null the moment the resolver is fixed — and that flip is the whole point of writing it down."* It flipped. Inverted to a REGRESSION case so the assertion holds the fix rather than the defect; it now matches its own CONTROL arm, which still guards against a vacuous pass. ## Verification - 21 scheduler suites — **361 green**, including the live PostgreSQL e2e - **`pnpm test:gate` green**; eslint and `tsc` clean - Changeset added; `check:changesets` passes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
